FORGE AND BIT HEATER.

App1ication filed June 14, 1923. Serial No. 645,451.

To all whom it may concern.

Be it known that I, ELLIS GREEN, a citizen of the United States, residing at: Mineral Wells, in the county of Palo Pinto and State I of Texas, have invented certain new and useful improvements in Forge and Bit Heaters, of which the following is a specification.

My invention relates to liquid fuel and gas burners and particularly to burners for forge and bit heaters; and the object is to equip forges for dressing oil well drill bits and similar purposes and which will distribute the fuel evenly and secure uniform heat and which will trap water, gasoline, or sediment from the fuel or steam and which will be highly efiicient in accomplishing such purposes and by which water may be used to soften the bits and to prevent scaling and by which much time may be saved in heating bits. Another advantage is the saving of time in equipping forges and the devices may be readily and quickly adjusted for burning either oil or gas in high or low pressure.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed outin the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a perspective view of the improved burner. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan'view of the forge and bit heater, illustrating the connection with a forge. Fig. 4: is a detail view, showing two kinds of burner jets.

Similar characters of reference are used to indicate the same parts throughout the several views.

The burner is provided with. a box 1 which is a separator, equalizer, and adjusting device for the various burner nozzles. High pressure or low pressure gas may be used as the heating fuel. A pipe 2 is provided for supplying steam or high pressure gas to the box 1. Means are also provided for supplying low pressure gas to the forge. A pipe 3 is provided for feeding low pressure gas directly to the blow pipes 4:. The pipe 2 is provided with a T-pipe connection 5. A pipe 6 for supplying steam is connected to one side of the T-pipe 5 and a pipe 7 for pp ying a i c nnected to the ether side of the T-pipe and these pipes 6 and 7 are adapted for alternate use, being provided with suitable cocks. For supplying low pressure gas, pipe 3 is connected to the pipe 7. When low pressure gas is to be used, connect pipes 3 and 7 for using or supplying the gas and connect pipes 2 and 6 for supplying steam at the same time, the steam being used to blow the gas into the forge, and, as is well known, the steam furnishes oxygen for increasing the heat. A yoke 8 is provided for adjusting the box 1 closer to or further from the blow pipes 42. Collars: 9 may be cast in tegral with the yoke 8 and the blow pipes 4t are screwed into the collars 9 and project into the forge 10. The box 1 is provided with nozzle ets 11 and 12. l Vhen high pressure gas is being used, such nozzles as 11 are used. High pressure gas is fed through the box 1, but low pressure gas is fed direct to the blow pipes 4: being forced in by steam which comes through box 1 and nozzles 11. When oil is to be used, the oil is fed direct to the blow pipes 4 through pipes 13 which are projected into collars 9 and steam is fed through box 1 and nozzles 12 for forcing the oil through the blow pipes i and also for supplying oxygen for aiding the combustion of the oil. The collars 9 have openings 14 for the pipes 13. When the oil is being used, the receiving ends of the blow pipes must be reduced. For this purpose fianged bushings! 15 are screwed into collars 9. When burning gas, no bushings 15 are used. When burning high pressure gas, the box 1 with its nozzles 11 is normally three inches from the ends of the blow pipes 4, but with some grades of gas, more satisfactory results are obtained by changing the position of the box 1, and this is done by sliding the box 1 on the arms 16 of the yoke 8. When the box 1 has been adjusted, it is held in place by set screws 17. When oil is being used, the box 1 should be about onehalf inch from the ends of the bushings 15. \Vhen using low pressure gas the box 1 with its nozzles 11 should be about one and onehalf inches from the collars 9.

Various changes in the construction, proportions, and arrangements of the several parts may be made without departing from my invention.

What I claim, is,--

11 In a terse a rn r sses i l w connected to said blow pipes for alternate use, andtnieans for direoting a. blast of. steam, lntov said blow pipes, for, driylng, gas or, oil,

through said blow pipes consisting of a control box adjustable relative to said blow pipes and provided with nozzles-1 and; steam! and gas pipe connections.

2. In a forge, a burner comprising blow. pipes projecting Within and without said forge, oil, feeding devicesaand gas feeding devicesoonnected to said: blow pipes :for'seleotive, use, a control boxspaced: and supported: from said blow pipes and: provided with nozzles: directed towards said blow pipes;.an;d; means for supplying steamyto said box for driving steam tQdndllQQ; oil or gas through said blow pipes 3. Ina forge, a burner comprising blow pipes projecting Within and, without; said ing,saiducontrolibox and means on said control box for positioning the control box on said yoke at difier'ent points of adjustment, and means for feeding steam ougas to said control boX.

In testimonywhereof, I set myvhand, this 3rd dayof May, 1-923:
